Water Potential (Ψ) deals with how the potential energy of a plant is measured. Relative movement of water and two systems, water potential and its movement, water is calculated using a specific factor, Megapascals (MPa). The two major factors that affect water potential include solute potential (Ψs) and pressure potential (Ψp).

Solute potential– Also called osmotic potential, solute potential is one of the measures of free energy and is always negative due to the presence of solutes.
Pressure potential– The…
